Application filed. May 18, 1922. Serial No. 561,830.

To all whom it may concern:

Be itknown that 1, JOHN S. G-ENDALL, a citizen of the United States,residing at W'oodmont, in the county of New Haven and State ofConnecticut, have invented a new andUseful Improvement in Jibing Buters;and I do hereby declare the following, when taken in connection with theaccompanying drawings and the characters of reference marked thereon, tobe a full, clear, and exact description of the same, and which saiddrawings constitute part of this application, and represent, in v Fig. la plan view, partly in section, of a jibing-bufier constructed inaccordance with my invention.

Fig. 2 a side view of the same.

Fig. 3 an end view thereof.

This invention relates to improvement in jibing-buffers adapted for usein sailing vessels. The sheets for the sails of sailing vessels passthrough a block, which is connected with a stationary eye, or with ablock which travels on the t-affrail, and when a vessel is jibed over,an enormous strain is placed upon the spars. The object of this,invention is to provide a yielding bearing for the sheet-blocks, so thatwhen a vessel is jibed, or running in a high sea, the strain on thespars, blocks and sheets will be relieved, and the invention consists inthe construction as hereinafter described and particularly recited inthe claims.

In carrying out my invention, I employ two bases 5 and 6 adapted to befirmly secured to the deck, railor other part of a sailing vessel, asrequired. These bases are formed with upwardly-projecting flanges 7 and8, between which extend rods 9 and 10 firmly secured to the flanges 7and 8 by nuts 11. Upon the rod 9 is a sleeve 12, and upon the rod 10 isa corresponding sleeve 13. The rods 9 and 10 extend through plates 14,15, 16 and 17. The plates 15 and 16 rest against the ends of the sleeves12 and 13, and between the plates 14 and 15 are springs 18 and 19, andbetween the plates 16 and 17 are springs 20 and 21. Extending throughthe plates 16 and 17 is an eye-bolt 22 havmg a nut 23 applied to itsouter end, and extending through the plates 14 and 15 is an eyebolt 24having a nut 25 applied to its outer end, and on the bolt 22, between Hthe plates 16 and 17, is a spring 26, and on the bolt 24, between theplates 14 and 15, is a sprlng 27. Passing through eyes 28 and I 29 ofthe bolts 22 and 24. are links so and 31,

the springs 18, 19 and 27. On the other hand, a strain upon the bolt 24will first draw the plate 14 against the pressure of the springs 18, 19and 27 and eventually, through the sleeves 12 and 13, be resisted by thesprings 20, 21 and 26, so that a strain in either direction is taken bysix springs. When a vessel is jibed over for the purpose of saving time,or for any other various causes, this device takes the strain off of thespars, and there is no sudden jerk or strain, as the jibing-buiferyields with the strain.

The device is also useful when a vessel is close-hauled on the wind,going to windward in a head beat sea, with the main sheet flat aft, asthe buffer will yield in the sea way and not tie the vessel up, so thatthe vessel can carry her sheets flatter and will beat to windward andkill foot faster.

I claim:

1. A jibing-bufi'er comprising two bases connected together by two rods,four plates on said rods, sleeves on said rods between the intermediateplates, eyebolts extending through the plates at opposite ends of thesleeves and connected with the outer plates, springs on said rods andbolts between said plates, and means for connecting a sheetblock withsaid eyebolts.

2. A jibing-buffer comprising two rods, means for suitably supportingthem in parallel position, four plates through which the said rodsextend, sleeves on said rods hetween the intermediate plates, eyeholtshaving their eyes between said sleeves, and extending outward throughsaid plates, means for coupling said eyebolts with the outer platessprings on said rods and eyebolts, and means for connecting asheet-block With said eyebolts.
